Description
Technical field
The present invention relates to a kind of carbon cloth, belongs to textile material technical field.
Background technology
Carbon fiber has low-density, high specific strength and specific modulus, high temperature resistant, resist chemical, highly thermally conductive, low-thermal-expansion etc.
Good characteristic, while there is high impact resistance, therefore the composite being made from it is often with there is excellent combination property.Research hair
Short carbon fiber reinforced material that is existing, being prepared compared to traditional molding methods, the fiber content of carbon fiber reinforced polymers can be very high,
Tensile strength and modulus can also improve an order of magnitude simultaneously.
Polyphenylene sulfide (PPS) is referred to as the sixth-largest special engineering plastics, has excellent heat endurance, good electric insulation
Property, corrosion resistance and from anti-flammability, and extrusion molding, continuous laminating, automation fiber/band laying method, bladder can be passed through
The processing such as molding and injection molding, so being widely used in the every field such as automobile, electronic apparatus and Aero-Space, market needs
The amount of asking increases severely.
PPS mechanical property can be effectively improved to PPS enhancings using carbon cloth, such as tensile strength and toughness, while
Heat resistance can be improved.Carbon cloth enhancing PPS materials are applied to many necks such as automobile, Aero-Space, military project, machinery at present
Domain.
But carbon cloth and PPS poor compatibility, PPS can not completely infiltrate carbon cloth.Carbon cloth strengthens
After the shaping of PPS composites, space and defect occurs on the surface of carbon cloth, influences the mechanical strength of composite, leads
The intensity of composite is caused not reach preferable effect.
The patent of Application No. 200910155010.1 discloses a kind of carbon fiber hybrid fabrics for impact resistant composite material,
It is to form carbon fiber wire and organic fiber silk mixed weaving, the toughness of carbon fibre composite can be improved, improve its anti-impact
Hit performance.But the caking property of carbon fiber and PPS can be improved by not mentioning.
The patent of Application No. 201610579342.2 discloses one kind and prepares carbon fibre fabric enhancing polyphenylene sulfide thermoplastic
The method of property composite, is to be submerged initially in carbon cloth in the acetone soln of epoxy resin to be pre-processed, with PPS films
Hot pressing forms prepreg, and prepreg is that PPS films are stacked alternately, and carbon fibre fabric increasing is prepared under certain temperature and pressure
Strong polyphenylene sulfide thermoplastic composite.This method causes carbon fiber wire and the interfacial adhesion power of polyphenylene sulfide matrix to pass through ring
The transitional function of oxygen tree fat is improved, but because epoxy resin and PPS interfacial adhesion is not also strong in itself, and carbon cloth
In the epoxy can not complete wetting, so improvement is not obvious enough.
The content of the invention
In view of the defects of above-mentioned prior art is present, it is an object of the invention to provide a kind of carbon cloth, it is possible to increase carbon
Fiber cloth and PPS compatibility, interfacial adhesion power, so as to improve the mechanical performance of carbon cloth enhancing PPS composites.
The purpose of the present invention is achieved by the following technical programs：
A kind of carbon cloth, it is formed by warp thread and weft yarns；Wherein,
The warp thread and weft yarn contain organic fiber silk, the organic fiber silk be PPSU filament and/or
